1) operated, either hy the opening or hv the closing of a door, for the purpose of ighting and putting out one or more electric lights.

The invention applies to a switch that is 5 autonnitically operated to close the circuit and light up a dark room or closet when the door is opened in order that the apartment may be inspected, and open the circuit and darken the room or closet, when the 0 door is closed, or which effects the opposite,

that is, which operates to close thc circuit and light up a dark room or toilet when the door is closed, and open the circuit and extinguish the light when the door is opened. 5 The object of the invention is to provide a very simple, cheap and small switch which can be conveniently arranged in u mort-isc in a door stile or in a door frame, as desired, and which will operate surely and quickly 0 when the door is opened and closed, being actuated one way by the' pressure of the door when the door is closed, and the oth-:r way, when the door is opened, by ax spring that is made tense by the closing of the door. 5 The switch illustrated in the drawings is designed to be inserted into a door frame, and, when the door is closed to be held with the circuit open and thfl actuating spring under tension so that at. soon as the door is 0 opened the spring will cause the switch to o rate and close` the circuit. Without c ringing the construction of the operating mechanism in any respect, but by merely reversing thc lposition of the fixed contacts the opposite effect may be accomplished,

that is, when the door is closed the circuit will he held closed by the door, and when t-he doot` is opened the circuit will be opened by the torce of the actuating spring which was put under tension bythe closing of the Figure 1 of the drawings'showa on .natural scale, a plan of u complete switch which cnil odies the invention.

Fig. Ltshows an elevation of the opposite side of the switch mechanism. Fig. 5 shows a plan of the switch mechanism. Fig, 6 shows an edge view of the. mechanism. Fig. 7 shows a central section of the mechanisxn. Fig. 8 shows on natural scale, a plan of the receptacle in which the switch mechanism is located, with the holding lugs and fixed contacts in place.

The receptacle l may be made of porcelain or any other suitable insulating material. This receptacle is preferably oblong in shape and at its ends is provided with perforated lugs 2 for the screws used to fasten the rcceptacle in place. Over the top of the receptacle is placed a cover plate 3, usually of brass, which is held in place by a screw 4, and through which the single push button 5 projects in such manner that it will be pushed inward by a part of a closed door when the switch 1s in use.

The mechanism supporting frame ha: a hase 6 which is fastened by screws to the bottom of the receptacle, and sides 7 which support an arbor 8. The top of one side of I the frame is bent over to form a guide 9 for the push button, and also to provide for the threaded perforation 10 designed to receive the screw which holds the cover in place. f

Pivoted on the arbor are arms 11. These arms are preferably connected ne'ar the arbor so they will move as one piece. A finger 12 which is secured to the inner end of the push button, is connected by a stud 13 with one of these arms, A spring 14, which is coiled about the arbor, has an end 15 engagingthe base of the frame and an end 16 engaging a tion of one of the arms in such manner that the tension of the spring normally holds the free ends of the arms upwardly and the push button, connected therewith, projecting outwardly. When the button is pushed inf ward the spring coiled on the arbor is given more tension, and as soon as the pressure is relieved the button and free ends of the arms are thrown violently outward by this spring 7 which is somewhat stiff.

Pivoted to the arbor' are the ends of a pair of arms which are connected so as to form a yoke 17. Attached to the outer or free end thv t'rnmv with its :Ixis vninvitling with thv JOHANN I. vIeTItIIstIN.
